Chlamydia requires a prescription antibiotic to treat, so you’ll need to get tested and receive a prescription from a healthcare provider. There is no over-the-counter medicine that treats chlamydia. The good news is that the process is straightforward, the treatment is short, and you have several options for where and how to get it, including telehealth visits you can do from home.
You Need a Test Before You Can Get a Prescription
Before any provider will prescribe chlamydia medication, you need a confirmed positive test or a documented exposure. Testing is simple and painless. For women, the most accurate method is a vaginal swab, which you can often collect yourself in the clinic. For men, a first-catch urine sample (the first part of your urine stream) is the standard. If you’ve had oral or anal sex, your provider may also swab those sites separately, since chlamydia can infect the throat and rectum without causing symptoms there.
These tests use a highly sensitive DNA-detection method that picks up the infection more reliably than older culture-based tests. Results typically come back within one to three days, depending on the lab. Some clinics offer rapid testing with same-day results.
Where to Get Tested and Treated
You have more options than you might think:
- Your primary care doctor or OB-GYN. A regular office visit works. You can ask for STI testing at any appointment, or schedule one specifically for this purpose.
- Sexual health or STI clinics. Many cities and counties run dedicated sexual health clinics that offer testing and treatment regardless of your ability to pay or insurance status. These are often the fastest route from test to prescription.
- Planned Parenthood and community health centers. These provide STI testing and treatment on a sliding fee scale based on income.
- Urgent care clinics. Most urgent care locations can test for chlamydia and write a prescription on the spot if you test positive or have a known exposure.
- Telehealth services. Several online platforms let you order an at-home test kit, submit your sample by mail, and get a prescription sent to your pharmacy if results are positive. Since chlamydia antibiotics are not controlled substances, the prescribing rules are simpler than for many other medications. A video or phone consultation is typically all that’s needed.
If cost is a concern, public health STI clinics are your best bet. Many provide both testing and medication at no charge. You don’t need insurance, and visits are confidential.
What the Treatment Looks Like
The standard treatment for uncomplicated chlamydia is a seven-day course of doxycycline, taken twice a day. This is now the preferred first-line option because it clears the infection about 97% of the time for urogenital infections. For rectal chlamydia specifically, doxycycline is significantly more effective, with cure rates around 95 to 99% compared to the alternative.
That alternative is a single-dose antibiotic (azithromycin), which used to be the go-to because of its convenience. It still works well for vaginal infections, clearing about 93 to 94% of cases, but it’s notably less effective for rectal infections (around 78 to 83%). Most providers now default to the seven-day course unless there’s a specific reason you can’t take it.
You should avoid sex for at least seven days after starting treatment (or seven days after a single-dose regimen) to prevent passing the infection to a partner. If you take all your medication as directed, chlamydia is completely curable.
Getting Treatment for Your Partner
If you test positive, your sexual partner needs treatment too, even if they have no symptoms. In many states, a practice called expedited partner therapy (EPT) allows your provider to write a prescription or provide medication for your partner without your partner needing their own appointment. You simply bring the medication or prescription to them.
EPT exists because chlamydia reinfection is common when partners aren’t treated simultaneously. Not every state permits it, so ask your provider whether it’s available where you live. If it’s not, your partner will need their own visit, but many clinics can accommodate walk-ins or same-day appointments for known exposures.
Follow-Up After Treatment
Retesting is recommended about three months after you finish treatment. This isn’t to check whether the antibiotics worked (they almost certainly did if you completed the full course). It’s to catch reinfection, which happens frequently because partners weren’t treated or because of new exposures. If you’re retested too soon after finishing antibiotics, the test can pick up residual DNA from dead bacteria and give a false positive, so waiting at least three to four weeks is important if you’re testing specifically to confirm cure.
Chlamydia doesn’t cause lasting damage when caught and treated early. Left untreated, though, it can lead to pelvic inflammatory disease in women (which can affect fertility) and painful inflammation in men. That’s one more reason to get tested promptly if you think you’ve been exposed, even if you feel fine. Most people with chlamydia have no symptoms at all.
